WILLIAIVI N. BROWN, OF TILDEN, ILLINOIS.

MINEBS TOOL.

Application filed January 11, 1923.

T 0 all whom it may concern:

Be it known that I, lVILLIAM N. BROWN, a citizen of the United States, residing at Tilden, in the county of Randolph and State of Illinois, have invented a new and useful Miner-s Tool, of which the following is a specification.

The device forming the subject matter of this application is a tool adapted to be used by miners, and the invention aims to provide a simple but efficient means whereby a miner may have at his command, a tamp ing bar, a device for cleaning out a drill hole, and a device for extending the hole by drilling action, novel means being provided whereby the tool may be of adjusted lengths, and novel means being provided whereby the tamping head may be driven out of the tubular socket which carries it, at the will of an operator.

It is within the province of the disclosure to improve generally and to enhance the util ity of devices of that type to which the in vention appertains.

/Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combina' tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the drawings igure 1 shows in elevation, a device constructed in accordance with the invention, parts being broken away; Figure 2 is a perspective view showing the tamping end; Figure 3 is a perspective depicting the extension bar; and Figure 4 is a perspective showing the chug drill.

Tn carrying out the invention, there is provided a tubular socket 1. The numeral 2 marks a tamping head, preferably of frustoconical form and made of wood if desired, the head having a notch 3 in its edge for the passage of the fuse. The head 2 has a reduced neck 4 firmly seated in the socket 1 and defining a shoulder 5 abutting against one end of the socket.

An extension bar 6 is mounted for sliding Serial No. 612,120.

adjustment in the socket 1 and is held in place by a set screw 7 carried by the socket. The extension bar 6 terminates in a spoon 8 of any desired shape.

In practical operation, when the device is inverted from the position shown in Figure 1, the tamping head 2 may be used in the well known way. The effective length of the structure may be changed by sliding the extension bar 6 inwardly and outwardly in the socket 1, the extension bar being held in place by the set screw 7. In this way the device may be adapted to holes of different depths. If desired, the set screw 7 may be loosened, and the extension bar may be slid endwise in the socket 1, to drive the neck 4 of the head 2 out of the socket 1. If preferred, the extension bar 6 may be removed, and its place may be taken by a chug drill 9 01' other tool held in the socket 1 by the set screw 7.

From the foregoing it will be obvious that the miner has at his command, means represented by the head 2 for tamping, means represented by the spoon 8 for clearing out a. drill hole, and means represented by the chug drill 9 for extending the hole.

lVhat is claimed is 1. A device of the class described comprising a tubular socket: atamping head seated in the socket an extension bar slidable in the socket into and out of engagement with the tamping head to drive the head out of the socket and means for holding the extension bar in adjusted positions in the socket.

2. A device of the class described comprising a tubular socket; a tamping head mounted in one end of the socket; tools adapted for interchangeable mounting in the other end of the socket, and means for holding the tools in adjusted positions, one at a time, in the socket, one of said tools be .ing movable into and out of engagement with the tamping head to drive the head out of the socket.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
